Abstract

In Engineering Schools, labs for teaching forming processes by means of material conservation methods are generally equipped with the appropriate equipment and tools to exemplify the theory received in class. However, the use of simulation techniques to complement the formation is not usually widely extended, since their learning is not usually trivial.One of the material conservation forming processes is sand casting. This process is of great educational significance, since the theory that defines it sets the basis for understanding other related moulding processes. In this context, the use of simulations of the moulding process allows the visualization of practical examples, helping to explain more clearly the theoretical information explained in class.Therefore, in this research a simulation assisted analysis has been developed using the Inspire Cast by Altair software, of teaching parts made in sand casting. First of all, students have been shown by means of simulations, the defects that can be originated in a part manufactured by sand casting. The study has been carried out by redesigning the risers involved in the distribution system of the process, by means of the Chvorinov's rule.Finally, a series of conclusions have been achieved, among which the following one stands out: if the functional performance of the part manufactured by sand casting is to be taken into account, the cooling modulus criterion must be selected for the design of the riser. Although, in principle, the material required for moulding is much larger, the defects generated in the part will be considerably reduced.
教学用砂型铸造配流系统仿真分析
在工程学院,通过材料节约方法教授成型过程的实验室通常配备适当的设备和工具,以举例说明课堂上所接受的理论。然而,利用模拟技术来补充地层通常不会得到广泛推广,因为它们的学习通常不是微不足道的。砂型铸造是一种节约材料的成型工艺。这个过程具有重要的教育意义,因为定义它的理论为理解其他相关的成型过程奠定了基础。在这种情况下,使用模拟成型过程可以使实际例子可视化,有助于更清楚地解释课堂上解释的理论信息。因此,本研究利用Altair的Inspire Cast软件,对砂型铸造教学零件进行了仿真辅助分析。首先,通过模拟的方法向学生展示了砂型铸造零件可能产生的缺陷。该研究是通过利用Chvorinov规则重新设计工艺分配系统中涉及的立管来进行的。最后,得出了一系列结论,其中最突出的结论是:如果要考虑砂型铸造零件的功能性能,则必须选择冷却模量准则进行冒口设计。虽然原则上,成型所需的材料要大得多,但零件中产生的缺陷将大大减少。
